Using computers and DNA to count bacteria

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

Don't call them the Dirt Doctors, or Sultans of Soil, they're just clever Lab guys. A team from Los Alamos National Laboratory has a paper in this week's Science Magazine with a new way to count bugs in dirt. Bacteria, that is, in the highly complex world beneath our feet.

Nature paper: Burning asteroids may play 'more important climate role than previously recognized'

DOE/Sandia National Laboratories
Peer-Reviewed Publication

In a study to be published this week in the journal Nature, scientists from the Australian Antarctic Division, the University of Western Ontario, the Aerospace Corporation, and Sandia and Los Alamos national laboratories found evidence that dust from an asteroid burning up as it descended through Earth's atmosphere formed a cloud of micron-sized particles significant enough to influence local weather in Antarctica.

Sandia researchers to study techniques for arsenic removal from drinking water

DOE/Sandia National Laboratories
Grant and Award Announcement

Over the next several months a team of researchers from the National Nuclear Security Administration's Sandia National Laboratories will be studying different methods of arsenic removal at the Desert Sands Mutual Domestic Water Consumers Association (MDWCA) in Anthony in southern New Mexico.

Sandia completes depleted uranium study

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Sandia National Laboratories has completed a two-year study of the potential health effects associated with accidental exposure to depleted uranium (DU) during the 1991 Gulf War.

Sandia researcher shares European physics prize for work; observations transformed Z-pinch field

DOE/Sandia National Laboratories
Grant and Award Announcement

For the remarkable achievements of the multi-filament Z-pinch development in the recent years," Sandia researcher Tom Sanford shares the European Physical Society's Hannes Alfven Prize with Malcolm Haines, former director of London's Imperial College Plasma Physics Dept., and Valentin Smirnov, director of the Institute of Nuclear Fusion at the Kurchatov Institute in Moscow.

Team investigates Active Denial System for security applications

DOE/Sandia National Laboratories
Business Announcement

A multi-organizational team is adapting for DOE use a technology that can help keep security adversaries out of DOE sites that contain nuclear assets. The DOE Office of Security and Safety Performance Assurance (SSA) is exploring the potential to use directed energy weapons technology sponsored by the Department of Defense (DoD), named Active Denial Technology (ADT), to help protect DOE nuclear assets.

Synthetic aperture radar may soon be used for reconnaissance on small UAVs

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Researchers at the National Nuclear Security Administration's Sandia National Laboratories flew what is probably the world's smallest fine-resolution synthetic aperture radar (SAR) in May, making real-time images from the 6-kilometer range with a resolution of four inches. It was a first for the 25-pound instrument that may soon be used for reconnaissance on near-model-airplane-sized unmanned aerial vehicles (UAVs).

Sandia develops secure wireless technology

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Sandia National Laboratories in cooperation with Time Domain Corporation and KoolSpan Inc. has developed a secure wireless Ultra Wideband (UWB) data communication network that can be used to help sensors monitor U.S. Air Force bases and DOE nuclear facilities and wirelessly control remotely operated weapon systems.

Scientists put the squeeze on electron spins

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

University of California scientists working at Los Alamos National Laboratory have developed a novel method for controlling and measuring electron spins in semiconductor crystals of GaAs (gallium arsenide). The work suggests an alternative--and perhaps even superior--method of spin manipulation for future generations of "semiconductor spintronic" devices.

Sandia, FAA, NASA create computer model for fire detection in airliner cargo compartments

DOE/Sandia National Laboratories
Business Announcement

A project to improve the false alarm rate and to standardize the certification of fire detection systems in cargo compartments of commercial aircraft is underway with major participation by Sandia National Laboratories, the Federal Aviation Administration (FAA), and NASA Glenn Research Center. Sandia's role in the project was to develop a physics-based Computational Fluid Dynamics (CFD) model to analyze smoke transport in cargo compartments.
